Make sure you know how to boot the tablet in Recovery mode:
– Shutdown, then start it, in the moment “LENOVO” image appears on the screen, press “Volume Up” few times
– You can navigate through the menu with the volume buttons, and select option with the power button
– If everything ok, just reboot in normal mode

on the PC, go to command line, and navigate to that directory where you’ve unpacked the exploit download.

I’m sorry to report that this didn’t work for me. I have just bought my TPT and have not applied any OTA. Buildnumber is ThinkPadTablet_A310_02_0039_0089_US.

The only clearly suspicious parts are the
* expected failed update from external storage. I get an error about “assert failed” and my windows 7 starts trying to install some drivers but failed.
* After following “When wipe cache complete, press .” I got some “mkdir failed for …, file exists”

Then, after the reboot, I only get an “The system update failed. Please try again. Version: ThinkpadTablet_A310_02_0039_0089_US” message on the tablet, and /cache/recovery/pwn/su on “adb shell” gives me permission denied.
